Tömegáramlásmér

Tömegáramlásmér translates from Hungarian to mass flow meter. A mass flow meter is an instrument used to measure the mass flow rate of a fluid, which is the mass of fluid passing through a point per unit of time. This is distinct from volumetric flow meters, which measure the volume of fluid passing through per unit of time. Mass flow meters are often preferred because the density of many fluids can vary with temperature and pressure, which would cause inaccuracies if only volumetric flow were measured.

There are several types of mass flow meters, each operating on different principles. Coriolis mass flow meters are a common type. They utilize the Coriolis effect, where a fluid flowing through a vibrating tube experiences a deflection force that is proportional to its mass flow rate. Another type is the thermal mass flow meter. These devices typically work by measuring the amount of heat transferred from a heated element to the flowing fluid. The amount of heat transfer is directly related to the mass flow rate of the fluid. Other technologies include the turbine mass flow meter and the differential pressure mass flow meter, though these are less direct measurements of mass flow.

Mass flow meters find applications in a wide range of industries. They are used in chemical processing, oil and gas, food and beverage production, pharmaceuticals, and aerospace. Accurate measurement of mass flow is crucial for process control, material balancing, custody transfer, and ensuring product quality. The choice of mass flow meter depends on factors such as the fluid properties (viscosity, corrosiveness), flow rate range, accuracy requirements, and operating conditions (temperature, pressure).
